Title: Method for growing compound semiconductor layer on single-constituent semiconductor substrate and such semiconductor structure
Inventor: OTSUKA NOBUYUKI
IPC: H01L21/205
Filed: 1989-04-27
Abstract: PURPOSE:To enable a flat surface to be formed by avoiding formation of an island structure of buffer layer by using a compound semiconductor including an element with a strong affinity for an element such as silicon which constitutes a singleelement wafer as a buffer layer. CONSTITUTION:First to fourth and fifth elements are selected so that affinity of second and third elements to the first element is equal to or larger than that of the fourth and fifth elements to the first element and affinity of one element out of the second and third elements to the first element is larger than that of the fourth and fifth elements. Thus, the constituents element constituting a buffer layer is connected with the first element for constituting a substrate rapidly, thus covering the surface of the substrate. Thus, an island-shaped growth of the buffer layer is avoided, thus enabling the surface of the semiconductor substrate layer formed on the buffer to be formed flatly.
